To all whom it may concern:

Be it known that I, CLIFFORD R. BUR- LINGAME, a citizen of the UnitedStates, residing at Coe, in the county of Isabella and State ofMichigan, have invented a new and useful Casing for Concrete Tile, ofwhich the following is a specification.

This invention relates to molds for forming concrete pipes or blocks,and has for its object the provision of a simple device which may beeasily handled and which may be quickly released from the formed blockwithout injury to the block. This object is attained in the constructionillustrated in the accompanying drawing and the invention consists incertain novel features of the same as will be hereinafter first fullydescribed and then particularly pointed out in the appended claims.

In the drawings,Figure l is a side elevation of a mold embodying myimprovements. Fig. 2 is a view taken at right angles to Fig. 1, and Fig.3 is a horizontal section on the line 33 of Fig. 2.

In carrying out my invention, I employ two members 1 and 2 which, in theform illustrated, are semi-cylindrical and are adapted to completelyinclose the block, as will be readily understood. One of the members isprovided along its edge with lugs or brackets 3 which project outwardand are adapted to overlap the meeting edges of the other member, whilethe said other member is provided with guiding lugs 4 which are adaptedto extend over the meeting member and thereby aid in bringing the twomem bers into the proper engagement. The upstanding portions of thebrackets 3 are slotted or notched, as indicated at 5, and the saidslotted upstanding portions are adapted to be engaged by hooks 6 on theends of bails or handles 7 which are pivotally mounted upon the member1, as shown. These bails or handles are pivotally mounted between theears 8 on the member 1 and are held normally in such a position as toengage the brackets 3 by springs'9 coiled around the pivot rod 10 of thebails and having their ends engaging respectively the cross bar of thebail and the side of the mold member. Upon reference to Figs. 1 and 3 itwill be observed that the bails are arranged in pairs, one bail beingmounted adjacent each edge of the member 1 of the mold and having theircross bars or grasping portions ar- Specification of Letters Patent.

ranged close together whereby they may be readily grasped, as will beunderstood.

In using my improved mold to form a concrete pipe or block, the mold isset up on end, as illustrated in the drawings, with the meeting edges ofthe two members in contact and the hooks 6 at the ends of the bails orhandles engaging the upstanding brackets or lugs 3, as clearly shown.The concrete or cement is then placed within the mold in the usualmanner and, if so desired, a core block may be employed in connectionwith the mold in order to form a hollow block or pipe or the centralportion of the block may be bored out by a drill or similar tool whilethe cement is green. The mold may be set up on a pallet or simply placedendwise on a flat surface. If a pallet is employed the block will beleft to dry on the pallet and the mold is removed therefrom simply bycausing the handles or bails 7 to swing inward toward each other,thereby releasing the hooks 6 from their engagement with the lugs orbrackets 3 and consequently permitting the members of the mold to beseparated. The two members may then be withdrawn from the concrete blockand placed together upon the pallet after which another block may beformed, as before. If the block is to be carried to a different pointfor drying, the mold is grasped by one handle or bail only and may thenbe carried to any desired point without any liability of damage to theblock.

My device is extremely simple in its construction and arrangement ofparts and may be manufactured at a trifling cost. The members will befirmly held together when in use and when not in use may be readilynested so that a number of the molds may be stored within a small space.The springs within the bails will hold the bails positively inengagement with the lugs on the co-acting member of the mold and whenthe mold is lifted by one handle or bail, the weight of the mold and thecontained block will act with the spring to hold the members of the moldtogether. When the members or bails are pressed together against theaction of the springs, they will be disengaged from the lugs or bracketson the coacting member and the two members of the mold consequentlyquickly released from the cement block or pipe.

WVhile I have illustrated a cylindrical mold in the drawings, it will beunderstood that the device may be employed for the for mation of blocksof any cross sectional design and that either solid or hollow blocks maybe formed therein.

Having thus described my invention, What I claim is:

In a mold of the class described, a pair of mold members, one of saidmembers being provided with notched lugs at its edges, bails pivotedupon the other member and having cross bars in juxtaposition andaffording handle members, the sides of the said bails at their endsbeing formed With hooks to engage in the notches of the lugs upon thefirst mentioned member, and a Wire spring secured about the pivot foreach bail and having one end bearing against the outer surface of thesecond mentioned men1- her and its other end bearing against the crossbar of the related bail.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of tWo Witnesses.
